Re: 600kV voltmeter

Original poster: "Dr. Resonance" <resonance@xxxxxxxxxx>

Volts x Amps, of course, equals power.  As the waveform drops the power
drops.  Without power, especially current, the heating factor drops and the
streamer dies.  No power --- no streamer.

Erratic paths caused by stray ions and cosmic rays.
